It’s a question you might not have even known you wanted the answer to, but here it is – what did Ugly Naked Guy actually look like?

The character was a regular story-line starter in Monica and Rachel's rent-controlled New York apartment but viewers never clasped eyes upon his face.

Ugly Naked Guy only appeared twice in the comedy show, but his name was mentioned by Monica, Rachel and the gang countless times throughout the ten seasons.

In 2015, Huffington Post made it their mission to locate the actor who played the small part on two occasions but the task was a difficult one as his name was never listed in the credits.

Ugly Naked Guy physically featured in 'The One with the Giant Poking Device', where the group tried to prod him with a long pole made out of chopsticks, and in 'The One Where Everybody Finds Out', where Ross tries to attain Ugly Naked Guy’s apartment when he moves out.

For more than a decade since the show's finale, viewers presumed that Michael Hagerty, who played Mr Treeger on the show, was Ugly Naked Guy, however that fan theory has finally been proven wrong.

Actor Jon Haugen played Ugly Naked Guy in Friends

After dozens of failed attempts contacting producers, actors, casting directors, the publication finally found the identity of the mystery man.

Jennifer Bender from Central Casting arranged a meeting with between with the mystery actor, Jon Haugen.

Haugen admitted that the reason his identity remained a secret for so long was because Warner Brothers wanted people to have to guess who he was.

“The reason I never came forward was because I was just keeping it mellow because Warner Brothers was keeping it mellow. They wanted everybody to have a guess who I was," the actor said.

The man who played Ugly Naked Guy also voiced his hope for a Friends reunion.
